Hazards Summary
Rapidly and exothermically reacts with tissue water forming potassium hydroxide (responsible for corrosivity) and methanol; Not likely to cause skin sensitization or be carcinogenic; [OECD SIDS: Methanolates - 2006] Reacts violently with water; Self-heating, may catch fire; Causes burns; Inhalation may cause corrosive injuries to upper respiratory tract and lungs; [Alfa Aesar MSDS] See Methyl alcohol. See Potassium hydroxide. See Sodium methylate.
Chemical Dangers
Heating may cause violent combustion or explosion. Reacts violently with water. This produces flammable methanol and corrosive potassium hydroxide. The substance may ignite spontaneously on contact with moist air. The substance is a strong reducing agent. It reacts violently with oxidants. The substance is a strong base. It reacts violently with acid and is corrosive. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).
Hazard Classes and Categories
Flam. Sol. 1 (50.6%)
Self-heating substance or mixture - category 1
Self-heat. 1

First Aid Measures
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer immediately for medical attention.
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
Spillage Disposal
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Sweep spilled substance into covered dry plastic containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
